BTW what is interesting that with the modern Training we have the top velocities in MLB haven't really increased. chapman is a bit of an outlier often hitting over 103 but other than him the top velos are around 100 just like they were in the Prior decades. Nolan ryan threw just as hard as syndergaard or Randy Johnson.
what did Change is the average velocity. there are much less pitchers throwing 88 nowadays and average Velo is really up. the Training does help but there seems to be a border that can't be shifted.
